Answer:

27.1 inches

Explanation:

Volume of a cone = ⅓ × pi × r² × h

48 = ⅓ × 3.14 × 1.3² × h

h = (48 × 3)/(3.4 × 1.3²)

h = 27.1360193 inches

Answer:

27.1 inches

Explanation:

The volume of a cone is denoted by:
V=(1)/(3) \pi r^2h, where r is the radius and h is the height.

Here, we're already given that the volume is 48, so V = 48, and that the radius is 1.3, so r = 1.3. Plug these in:


V=(1)/(3) \pi r^2h


48=(1)/(3) \pi *1.3^2h

Now, solve for h by dividing both sides by (
(1)/(3) \pi *1.3^2):

h = 48 ÷ (
(1)/(3) \pi *1.3^2) ≈ 27.1 inches

Hope this helps!
